With the remarkable progress of photovoltaic technology, next-generation perovskite solar cells (PSCs) have drawn significant attention from both industry and academic community due to sustainable energy production. The single-junction-cell power conversion efficiency (PCE) of PSCs to date has reached up to 25.2%, which is competitive to that of commercial silicon-based solar cells. Currently, solar cells are considered as the individual devices for energy conversion, while a series connection with an energy storage device would largely undermine the energy utilization efficiency and peak power output of the entire system. For substantially addressing such critical issue, advanced technology based on photovoltaic energy conversion-storage integration appears as a promising strategy to achieve the goal. However, there are still great challenges in integrating and engineering between energy harvesting and storage devices. In this review, the state-of-the-art of representative integrated energy conversion-storage systems is initially summarized. The key parameters including configuration design and integration strategies are subsequently analyzed. According to recent progress, the efforts toward addressing the current challenges and critical issues are highlighted, with expectation of achieving practical integrated energy conversion-storage systems in the future.
随着光伏技术的显著进步，下一代钙钛矿太阳能电池（PSC）因其可持续的能源生产而受到了工业界和学术界的广泛关注。迄今为止，PSC的单结电池功率转换效率（PCE）已达到25.2%，与商用硅基太阳能电池具有竞争力。目前，太阳能电池被视为用于能量转换的独立装置，而与能量存储装置的串联连接将在很大程度上降低整个系统的能量利用效率和峰值功率输出。为了切实解决这一关键问题，基于光伏能量转换-存储集成的先进技术似乎是实现这一目标的一个有前景的策略。然而，在能量收集和存储装置之间的集成与工程方面仍然存在巨大挑战。在这篇综述中，首先总结了代表性集成能量转换-存储系统的最新进展。随后分析了包括配置设计和集成策略在内的关键参数。根据最近的进展，强调了为应对当前挑战和关键问题所做的努力，期望在未来实现实用的集成能量转换-存储系统。
